WINDMILL.

BECIFICATION forming; part of Letters Patent No. 278,842. dated June 5,1883.

I Applicationfiled October 18 882. (No model.)

To all whom it may concern:

Be it known that I, LYMAN WiL'oox, of Gone, in the county of Monroe andState of Michigan, have inventednew and useful Improvements inW'indmills, and I hereby declare that the following is a full, clear,and enact description thereof, reference being had to the accompanyingdrawings, which form a part of this specification. i

This invention relates to certain new and useful improvements in theconstruction of windmills and it consists in the peculiar constructionof the turn-table, and in the peculiar construction, arrangement, andvarious com.- binations of the parts, all as more fully here inatter setforth and claimed.

Figure 1 is a perspective view of my invention. Fig. 2 is an elevation,with the windwheel at right'angles to the position shown in Fig. 1.

In the accompanying drawings, which form a part of this specification, Arepresents a hollow standard, which is designed to be supported by anysuitable frame-work. \Vithin the upper end of this standard A is placedthe bent tube B, upon which the head C of the tail-vane D is rigidlysecured in any convenient manner, the head 0 being free to rotate up 011the end of the standard A, while the upper face of the head 0 serves asa rest for the turn-table E, which is sleeved'upon the upper end of thetube 13. The upper face of the head (3 is slightly inclined, as shownclearly in Fig. 2, while the hub F of the turn-table E has its lowerface, which rests upon the head 0, similarly formed. The turn-table E isprovided at one side with the arm G, from which rises the standard H,provided with suitable bearings, H, in which the wheel-shaft I isproperly journaled, the outer end of which carries the wind-wheel J. Theinner end of this shaft I is provided with a crank-pin, a, to which oneend of the connecting-rod K is secured, the opposite end engaging withone arm ofthe bellcrank lever L, which is properly pivoted in the upper.end of the standard M, resting on the turn-table E, while to theopposite end or arm of this bell-crank lever is secured the pump-rod N,which passes down through the tube B, as in the ordinary manner. Risingfrom the stem of the ta-ilrvane is a standard, 0, in-the upper end ofwhich is properly pivoted the bell-crank lever P, one arm of which isconnected by a rod, R, to the turn-table E, upon the side opposite tothat which supports and carries the wind-wheel. The other .arm of thisbell-crank lever P is provided with a rod, S, which projects down towithineasy reach from the ground, and upon this arm is properly securedthe sliding weight T.

In practice, the parts being in position as shown in Fig. 1, the windwill strike directly upon the face of the wind-wheel, causing it torevolve, and, by the connections hereinbefore named, impart areciprocating motion to the pumprod. As the wind increases in force theaxial center of the wheel, being at one side of the center of theturn-table, will cause the turn-table to turn upon the head 0 and assume the position in a heavy wind shown in Fig. 2 in which the axialcenter of the wheel is at right angles to the axial center of thetail-vane and head. This movement causes the rod R to draw upon itsrespective arm of the bell-crank lever P and raise the arm'which carriesthe sliding weight T, and which latter in this movement will slide downits arm of the lever to or near its pivotal point within the standard.As the wind decreases in force the gravity of the turn-table and wheelwill naturally cause them to assume their original position and slidedown the incline upon the head 0, while at the same time the slidingweight T will likewise assume its original position near the outer endof the lever which supports it, and this weight may be graduated so thatthe mill or wheel may be thrown out of wind by either a light or a heavywind, as

it is evident that before the wheel can assume the position shown inFig. 2 the wind must have reached that force sufficient to cause thetable to slide upon the incline and also to overcome the gravity of thesliding weight.

.W'hat I claim as my invention is In a windmill constructedsubstantially as described, and in combination with the turn-table E,formed with suitably-inclined bearing-surfaces and anoppositely-inclined supportinghead,the bell-crank lever P, theconnecting-rod R, sliding weight T, standard 0, and suitable-ta-il-vane,arrangedzand adapted for automatically controlling the action of themill, substantially as set. forth.

2. In a windmill, and in combination with the tube B, head C, formedwith inclined bearing-surfaces, and the tail-vane D, constructed asdescribed, the turn-table E, resting upon such head C and provided withoppositelyinclined faces, substantially as and for the pur posesdescribed.

3. In a windmill, and in combination with a head, (1, having inclinedbearing-surfaces, and the turn-table E, having bearing-surface S,resting upon said head 0 and oppositelyinclined thereto, the wheel J,journaled in suitable bearings, H, arranged tangential to the peripheryof said turn-table and head, sub stantially as specified.

4. A windmill consisting of the tube B,

weight T, when constructed, arranged, and

operating substantially as and for the purposes herein set forth.
